Bluescat, the graph clearly shows that Man appeared before Woman, by thousands of years, regardless of cranium capacity. It's just simply ridiculous. Why can't scientists these days, do science?
If that is your understanding of that chart then you should retire from the science forums here. You are not equipped with the knowledge necessary to carry on any discussions at all. I am thunderstruck by your conclusion!
The chart shows fossils that have been found. There are periods when the only fossils found have been male. That is all it means.
You are hopelessly out of your depth.
